4 Claims. (Cl. 139-154) This invention relates to devices for clamping lug straps to picker sticks of looms, and in particular improvements in the structure of lug strap supports wherein the clamping frame and mounting plate are formed in two pieces instead of one and wherein the parts are clamped again-st a picker stick with a common U-holt.

The purpose of this invention is to simplify and improve the construction of lug strap supports to provide a more economical structure and also to provide a frame that eliminates cutting and damaging of lug straps whereby the life of lug straps held by the support is extended indefinitely.

With this thought in mind this invention/contemplates a lug strap support in which the frame through which the lug strap passes is formed of half round rolled stock whereby smooth polished surfaces, only, are contacted by the lug strap and in which the frame is supported by a U-bolt and a mounting plate, the mounting plate heing also formed of rolled plate or stock material.`

The object of this invention is, therefore, to improve the structure of lug strap supports whereby the supports are adapted to be economically constructed and in which lateral movement thereof on picker sticks is substantially impossible.

Another object of the invention is to provide an improved lug strap support for looms in which contacting surfaces ofthe support and lug strap are relatively smooth.

A further object of the invention is to provide an improved lug strap support for looms in which the support is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a substantially rectangular shaped frame having a lower bar with end bars extended upwardly from ends thereof and with inwardly extended sections having eyes or connecting means on ends thereof integral with the end bars, a mounting plate having an arcuate shelf on the lower edge and having picker stick gripping ngers extended therefrom, and a U-bolt having a flat portion positioned to engage a picker stick and having threaded studs with nuts thereon extended through the mounting plate and eyes of the inwardly extended section of the frame.

Other features and advantages of the invention will appear from the following description taken in connection with the drawing, wherein:

Figure 1 is a front elevational view showing the improved lug strap support with part of an end of the shelf at the lower end of the mounting plate broken away to show a notch for receiving a rail of the frame therein.

Figure 2 is a vertical section through the support taken on line 2-2 of Figure l, also with parts broken away and with parts shown in elevation.

Figure 3 is a plan View of the improved lug strap support also with parts broken away and with parts shown in section.

Figure 4 is a detail looking upwardly toward the lower side of the lower rail of the lug strap supporting frame.

Figure S is a View similar to that shown in Figure l States Patent with the parts shown on a reduced scale illustrating a modification wherein the eyes of the inwardly extended sections of the lug strap holding frame are omitted.

Figure 6 is a vertical section taken on line 6-6 of Figure 5 showing the frame and mounting plate clamped to a picker stick with a conventional U-bolt.

Figure 7 is a detail illustrating a mounting plate of the type used in Figures 5 and 6 and which is adapted to be used with lug strap holding frames of various designs.

Referring now to the drawing, wherein like reference characters denote corresponding parts, the improved lug strap support of this invention includes a frame having a lower rail l0, end rails 11 and 12, inwardly extended sections 13 and 14 extended from the upper ends of the end rails 1l and 12 and having eyes 15 and 16, respectively, on their upper ends, a mounting plate 17 having an arcuate shelf 1S on the lower edge and a Ubolt including a section 19 of flat material with studs 20 and 2l extended from ends thereof and with nuts 22 and 23 threaded on the studs.

The shelf i8 on the lower edge of the mounting plate 17 is provided with a slot 24 through which a strap 2d, preferably of leather', extends and the lower part of the strap extends through a recess 26 in the lower rail lil of the frame. The lower rail l0 is provided with a flange Z7 that extends downwardly, or outwardly, as shown in Figure 2, and the upper end of the strap 25 is provi ed with a cross-piece 23 that is secured to the strap with a rivet 29 and that prevents the strap dropping downwardly through the opening or slot 24.

The mounting plate 17 is provided with fingers 30 and 3i, which may be struck from openings 32 and 33, respectively, in the plate 17, and which are positioned to engage the sides of a picker stick, as indicated by the numeral 34. With the lingers 3i) and 3l in engagement with side surfaces of the picker stick lateral movement or twisting of the lug support is substantially eliminated.

The gripping surface of the plate i7 is also provided with a gripping ridge 35 that is stamped from a groove 36 in the outer surface of the plate to facilitate rigidly clamping the mounting plate to the picker stick. It will be understood that both the ridge 35 and fingers 3h and 31 may be used in combination or either one may be used as desired.

I he studs 2t) and 2l may be provided with lock washers, as indicated by the numeral 37.

ln the design illustrated in Figures 5, 6 and 7 the lug strap support is formed with a rectangular shaped frame having a lower horizontally disposed rail tti with upwardly extended end rails 41 and 42 and with ends i3 and 44 extended from inwardly sloping sections l5 and 46, respectively, a mounting plate 47 having a shelf S3 on the lower edge and having openings 49 and 5@ for a U-bolt Si therein and with the U-bolt provided with nuts 52, lock washers 53 and a holding plate S4.

ln this design the upper portions of the end rails -il and 42 extend over the arcuate edges of the shelf 43 and the ends 43 and 44 are provided with notches 55 and S6 that receive the Ubolt 5l. in this design a leather strap S7 is positioned between the plate Li7 and a picker stick as indicatedby the numeral S8 and the parts are secured in position by clamping the frame and mounting plate to the picker stick with the U-bolt.

It will be understood that a frame for holding a lug strap, such as the lug strap 59, may be used independent of the mounting plate with frames such as the frames formed with the parts 1li, 11, 12, 13, 14, 15 and lr6, shown in Figure l, or with the parts 4d, 4l, 42, 43, 4, 45 and 46, as shown in Figure 5, and these parts which may be made of rolled stock, such as rolled cold steel may be secured directly to a picker stick by U-bolts as shown in Figures 3 and 6, respectively.

By this means a lug strap support may be positively clamped to a picker stick with a frame formed of rolled steel stock, or other suitable material and separated ends of the frame may be gripped by a U-bolt or other suitable clamping means with the separated ends provided with eyes or notches and also with straight ends with the eyes and notches omitted.

It is contemplated in certain instances to use the lug strap support of this invention in an inverted position, such as with the parts turned upside down on the picker stick, the apparatus functioning equally well in an inverted position.

It is believed that other modifications, within the scope of the appended claims, may be made in the design and arrangement of parts without departing from the spirit of the invention.
